Patent EP-0466679-A1 (EP)
Inventor: WIGLEY GRAHAM DR
IPC: G01N15/14
Filed: 1991-07-02
Abstract: In the combustion of fuel mists, the fuel drops are exposed to a wide temperature range and this results in unduly large differences in the density and the reflective index of the drops. A determination of the drop size by phase doppler anemometry of the conventional type therefore only yields inaccurate values. In order to measure the temperature effects quantitatively, it is proposed that, to determine the temperature of the drops at a first scattering angle  PHI 1 for which the phase shift of the scattered radiation with respect to the primary radiation depends essentially only on the drop size D, the phase shift P PHI 1(D) is measured and the drop size D is determined from it, that simultaneously, at a second scattering angle  PHI 2 for which the phase shift of the scattered radiation with respect to the primary radiation depends on the drop size D and the refractive index n of the drops, the phase shift P PHI 2(D,n) is measured and the refractive index n of the drop is determined from it, and that the density and the temperature t of the drop are derived from the size D and the refractive index n. <IMAGE>

Abstract: Selon un procédé de manipulation de particules diélectriques de dimensions microscopiques, les particules sont exposées à un champ électrique. Selon des procédés connus, les particules sont exposées à des champs électriques inhomogènes et sont polarisées par ceux-ci. Les particules polarisées se déplacent dans la direction où l'intensité du champ est la plus élevée. Ces procédés ne permettent pas de renverser le sens de déplacement des particules. Les particules s'enrichissent au niveau de l'électrode, de sorte qu'elles ne peuvent pas être retenues dans un espace libre. Selon le procédé décrit, les particules sont exposées à un ou plusieurs champs de haute fréquence se déplaçant dans des directions prédéterminables, de sorte qu'une force est exercée sur les particules qui les met en un mouvement fortement asynchrone par rapport au champ. Un dispositif de mise en oeuvre de ce procédé permet de manipuler des particules avec beaucoup de souplesse. Des électrodes agencées en ligne ou en cercle permettent de déplacer les particules sur des voies linéaires dans toutes directions voulues ou à travers des microstructures ramifiées; elles peuvent être triées selon leurs propriétés diélectriques et retenues sans contact. L'invention trouve des applications sans le domaine de la biotechnologie et des techniques de microtransport, de focalisation et de triage moléculaires.

Abstract: On décrit un rhéomètre, comprenant un récipient destiné à un fluide devant être mesuré, un agencement de rotor et stator concentrique, et un circuit servant à faire circuler le fluide, qui comprend une pompe produisant un écoulement pulsant et non laminaire dans le récipient. Lorsqu'on utilise la pompe pour créer un écoulement à la fois turbulent et pulsant, la matière particulaire peut être maintenue en suspension et l'écoulement amené à travers le système de mesurage, alors que tout effet rhéologique produit par le système de pompage sur le fluide est introduit indépendamment des effets rhéologiques produits par le système de mesurage lui-même. Le pompage peut ainsi se poursuivre pendant que le mesurage est effectué.

Abstract: This invention is for an object moving actuator composed of a stack of independently controllable layers which convert thermal exobaric pulses into mechanical motion. Each layer can be a lifter for moving the stack normal to the object to be moved or a tangenter for moving the stack tangentially to the object. Each layer has a plurality of chambers having a heat source (36) and a thermal expansive material (40) contained therein. The heat source (36) is controlled by a controller to generate a heat pulse which expands the thermal expansive material (40) thereby moving a rolling barrier (32) to make the layer move normally or tangentially. Preferably two pair of actuator stacks work together to alternately engage and move the object. The first pair makes contact with the object by lifter motion and moves the object by tangenter motion while the second pair is lifted off the object and retraces to get into position to contact and translate the object. When the actuator engages the object at the same speed the object is moving so that no frictional rubbing occurs, smooth walking motion is acheived.

Abstract: An apparatus for developing an image on a photoconductive surface (34,44). The apparatus includes a first roller (36) positioned adjacent to the photoconductive surface (34). Negatively charged toner is supplied to the surface of the first roller (36) where the toner electrostatically adheres, either in a uniform layer or a variable layer, to the surface of the first roller. The negatively charged toner electrostatically adhered to the surface of the first roller (36) is then transferred to the photoconductive surface (44). The apparatus may also include a second roller (38) held at a positive charge relative to the first roller (36) for electrostatically transferring toner from the second roller to the first roller. Alternately, the positive charge on the second roller relative to the first roller may be produced by placing a negative charge on the first roller or by placing a negative charge on the second roller and a more negative charge on the second roller. By placing a negative charge on the second roller, the toner will also be negatively charged before transfer to the first roller.
